To set V/f curve mode (S0.00) of EFC 3600 frequency converter, use register address
0x0200 (0x02=S0-group, index 0).
Access to a non-existing function code will be acknowledged with exception code 3
(see chapter 13.2.3 "ModBus Function Codes and Message Format" on page 174 ).
● Communication control registers
The address of command word register for communication control is 0x4000. This reg‐
ister is write-only. The frequency converter is controlled through writing data into the
address. The definition of each bit is shown in table below:

Fig.13-23: Communication control registers
The address of frequency setting register for communication control is 0x4001. This
register is for read and write. When [b1.00] "First frequency setting source" is set to "5:
Given via communication", the frequency converter can be set with writing data to this
address.
If the communication frame check is successful (CRC valid), the frequency converter
always accepts the content of the control word. Any conflicts (e.g. run command and
stop command active at the same time) are resolved by the application functionality
(RUN/STOP generator, jog control, ...). This assures that the inverter will always react
in the same manner, independent of the run command source.
● Communication state feedback registers (0x5000)
